Microbiologically influenced corrosion (MIC) of concrete in sanitary sewer pipe and manholes is the result of dilute sulfuric acid (H2SO4) dissolving the cement matrix. The acid is produced by a complex series of chemical and biochemical reactions. The objectives of this paper are: (1) to review the basic science of the MIC process starting with the [...]

After being established in 1967, the commercially available murine Leydig cell tumor line I-10 has been used in almost 50 published studies. I-10 has not been characterized, either at the chromosomal/ cytogenetic level or the genetic level, similar to many other murine tumor cell lines. In this study, we performed molecular karyotyping and multicolor [...]

Robertsonian translocations (RTs) are very common balanced structural chromosome rearrangements in humans. Due to alterations in the chromosome segregation pattern and the formation of unbalanced gametes and embryos, the carriers of RTs have a significant risk of reproductive failure. For over 30 years, fluorescent in situ hybridization (FISH) has been [...]

The rational design of efficient electrocatalysts for oxygen reduction reaction (ORR) is the key to developing fuel cells and metal-air batteries. Carbon-supported iron-based materials, as the most promising electrocatalysts for ORR, have drawn much attention as they are cost-effective and exhibit high activity. In this work, a three-dimensional (3D [...]

Syncope is characterized by a transient and rapid loss of consciousness for a short duration, with full spontaneous recovery within minutes. Syncope causes up to 2% of all emergency medical consultations. The incidence of syncope is similar in men and women, is higher in old patients (slightly higher in old women). The prevalence of syncope is up to [...]

The term chimera refers to an organism with cell lines from two or more distinct zygotes. Human chimerism may occur naturally or artificially. Although rare, advancements in genetics and genomics have resulted in the identification of additional natural human chimeras. Three forms of naturally occurring chimerism have been documented in humans: blood [...]

Expanded industrial globalization has resulted in the release of high concentrations of heavy metals into environmental water sources and soils. Phytoremediation may help to remove these heavy metals from contaminated soils. Tall fescue (Festuca arundinacea Shreb.) exhibits phytoremediation potential due to its endurance and high stress tolerances. [...]
